Centralized aerobic mud pulling sedimentation tank

Abstract

The invention discloses a centralized aerobic mud pushing sedimentation basin, which is characterized in that a main basin body is internally provided with an aerated pipeline; a mud reflow pump and a mud discharging pump are arranged at the side in the main basin body; a water inlet pipe positioned outside the main basin body is provided with a medicament feeding point; the main basin body is also internally provided with a medicament feeding point. The different parts of the invention are tightly matched through pipelines; the structure is more rational and the water distribution is more even so as to realize complete mud water internal circulation. The aerated pipeline provides enough dissolved oxygen to the mud microorganism in the basin so as to strengthen the organism function. The multi-point feeding of a plurality of kinds of medicament in and out of the basin body further strengthens the physical flocculation function. A lifting dasher and a mud reflow pump are controlled by a frequency conversion motor, and can be flexibly adjusted according to the factual conditions so as to guarantee the water quality. A concentrated mud pushing machine can realize the centralization of the mud and the concentration of the mud, thereby being suitable to be used in strengthening the normal treating of the water plant, in the sewage plant treating and the special water treating.

Description

Technical field: [0001] The invention relates to the technical field of biological action sedimentation tanks, in particular to a centralized aerobic mud pushing sedimentation tank for the combination of biodegradation and mixed flocculation and sedimentation in the conventional treatment of water supply plants, sewage treatment plants and special water treatment . Background technique: [0002] At present, there are advection sedimentation tanks, mechanical agitation clarifiers, and inclined tube sedimentation tanks for conventional treatment in waterworks, sewage treatment and special water treatment sedimentation processes. Among them, although the conventional water quality of the advection sedimentation tank can also meet the requirements of the water to be filtered, and it is easy to manage and resistant to impact loads, it occupies a large area and has a large amount of muddy water, especially in the north. The low-temperature and low-turbidity water treatment effect ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a centralized aerobic mud pushing sedimentation tank, which can give full play to the role of indicators such as biodegradable organic matter, nitrogen and phosphorus, further reduce the floor area of ​​the tank body, increase the scale of treatment, and solve the problems currently existing in Problems such as low surface loading rate and uneven water discharge in precipitation treatment
